Whakaitihia te pānga o te tangata ki te hanga o ngā tauera waipiro: Mai i te mahi ā-ringa ki te mahi aunoa

He aha te Aunoatanga o te Hanga Horoi Waipiro?

Ko te aunoatanga o te hanga horoi waipiro he tukanga whakakapi i te whakahaere ā-ringa, te inenga, me ngā mahi tākai ki ngā taputapu kati-porowhita, haumaru-pahūtanga i hangaia mō ngā taiao waipiro isopropyl (IPA). Mā tēnei huarahi ka whakakorea te pā tika o te tangata ki ngā kohu mura, me te pupuri tonu i te kounga me te kaha o te hua.

Ka whakauruhia e ngā pūnaha aunoa hou te inenga e whakahaerehia ana e te servo, ngā rūma whakakī kua katihia, me te aroturuki tonu i te kohu hei waihanga i ngā āhuatanga mahi haumaru ake. He rerekē ki te aunoatanga o ngā takai tuku iho, me whai wāhanga motuhake kua whakatauria e te ATEX me ngā hoahoa ātete-pahū ngā pūnaha horoi waipiro hei whakahaere i ngā wero ahurei o ngā taiao whakarewa mura.

He aha te take e puta ai he mōrearea haumaru i te hanga horoi waipiro ā-ringa

Ngā Tūponotanga Matua o te Whakamāramatanga

Ngā Mōrearea o te Manawa Kohu:

Mā te hanga ā-ringa i ngā horoi waipiro ka tūpono ngā kaimahi ki ngā kukū kohu IPA morearea e neke ake ana i ngā rohe haumaru o te Wā Taumaha (TWA) o te 400 ppm mō ngā haora 8. I ngā wā tino pukumahi o te hanga, ka eke te kukū kohu ki te 800-1200 ppm i ngā wāhi kāore i te pai te hauhautanga.

Ko ngā tohu noa ko:

● Te whanoke me te koretake o te hinengaro i roto i te 15-30 meneti o te pānga

● Te mamae o te upoko e mau tonu ana mō ngā haora 2-4 i muri i te mahi

● Te riri o te manawa me te wera o te korokoro

● Te whakaiti i te mataara, te whakanui ake i te tūponotanga o ngā aituā mā te 35%

Ko ngā rohe mōrearea nui ko ngā teihana whakakī hinu e ringihia ā-ringa ai te IPA e ngā kaiwhakahaere, ngā wāhi tuwhera-mākū e mimiti ai te whakarewa i ngā papa, me ngā rohe hiri-mua e kukū ai te kohu i mua i te tākai.

Ngā Mōrearea o te Pa atu Tika:

Ka pā te kiri me te kanohi i te wā e whakamahia ana te inenga ā-ringa, e whakawhiti ana i te ipu, e whakahaere ana hoki i ngā tikanga tauira kounga. Ka taea e te mimitinga o te IPA ki te kiri te whai wāhi atu ki te 20% o te kawenga katoa o te pānga, ā, ka pāngia te 40% o ngā kaiwhakahaere ā-ringa i ia tau.

Ka puta he mōrearea mura i te kohikohinga hiko pūmau mai i ngā PPE hangai, inā koa ka honoa ki ngā ipu whakarewa kāore i te whenua me ngā taputapu whakawhiti. Ka noho ngā motuka, ngā pūoko, me ngā huānga whakamahana kāore i te whakatauranga hei pūtake mura pea i roto i ngā taiao nui te kohu.

Ngā Take Haumaru Whakahaere:

Ko ngā mahi ā-ringa e auau ana, tae atu ki te hiki i ngā ipu whakarewa 50-pauna, te tākai ā-ringa i ngā hua kua oti, me te whakarerekētanga auau i ngā taputapu, ka hua ake he whara ahotea ergonomic ka pā ki te 25% o ngā kaimahi whakaputa i ia tau.

Ka piki ake ngā hapa i puta mai i te ngenge i ngā wā roa o te mahi, ā, ka hua ake ēnei:

● Te hiri o te taupoki kāore i oti (12% o te mahi ā-ringa)

● Para kua tino mākū (8-15% te ngaronga rauemi)

● Ngā hapa o te tutuki i ngā whakaritenga PPE (i kitea i roto i te 30% o ngā kitenga o te huringa mahi)
